摘要
为了研究夏季横断山不同地区大绒鼠(Eothenomys miletus)的雌鼠繁殖情况,测定了哀牢山、剑川、丽江、香格里拉和德钦地区怀孕雌鼠的繁殖期体重、胎仔数和胎仔重。结果表明:哀牢山、剑川和丽江地区大绒鼠的繁殖期体重、胎仔数和胎仔重明显高于香格里拉和德钦地区。以上的结果说明,环境温度和食物资源的差异是影响雌性大绒鼠繁殖质量的主要因素。
In order to study the reproduction of Eothenomysmiletus in different areas of Hengduan mountain regions in summer, body mass, litter size and litter weight of pregnant female voles in Ailao Mountain, Jianchuan, Lijiang, Shanggelila and Deqin were measured. The results showed that body mass, litter size and litter mass in E. miletus of Ailao Mountain, Jianchuan and Lijiang areas were significantly higher than those of Shanggelila and Deqin. All of the results suggested that the difference of environmental temperature and food resources were the main factor affecting the reproductive quality of female voles.
